111 tools for AI assistants, free to start. Exact answers instead of guesses: IBAN and VAT checks, VAT amounts, Dutch public holidays and working days, cron parsing, regex testing, JSON, CSV and Base64 transforms, UUIDs, Dutch test data. Render tools turn HTML or any URL into a hosted PDF or screenshot, make QR codes, merge and split PDFs, resize, convert and compress images, and read JavaScript-rendered pages as Markdown. Memory tools give the agent a private key-value store between sessions. Workflow tools run the multi-step workflows saved on your account by id.
Remote streamable HTTP endpoint: https://toolforte.com/api/mcp/mcp. For stdio-only clients: npx -y toolforte-mcp (npm). Setup guides per client (Claude, Claude Code, Cursor, VS Code, ChatGPT, Windsurf, Gemini CLI): https://toolforte.com/mcp
Utilities and memory are free. A free API key adds a monthly credit balance for renders and workflows; pass it as Authorization: Bearer tf_....
Список инструментов сервера (60)
Технические названия из tools/list. Нужны только разработчикам.
| text_diff | Compute an exact line-based diff between two texts with add/remove/unchanged stats. |
| format_json | Validate and pretty-print JSON with a real parser. Returns formatted JSON or the exact parse error. |
| markdown_to_html | Convert Markdown to HTML deterministically. |
| csv_to_json | Parse CSV data into JSON with delimiter auto-detection and quoted-field handling. |
| url_encode | URL-encode or decode a string with exact percent-encoding. |
| base64 | Encode text to Base64 or decode Base64 to text, byte-exact. |
| test_regex | Run a JavaScript regular expression against a test string using a real regex engine. Returns all matches with capture groups and indices. |
| convert_color | Convert a CSS color between HEX, RGB, HSL, and HSB with exact math. |
| password_strength | Analyze password strength with entropy-based scoring and concrete feedback. Do not log or store the password. |
| count_words | Exact word, character, sentence, and paragraph counts plus reading time for a text. |
| parse_cron | Parse a cron expression into a human-readable description and the next scheduled run times. Exact cron semantics: use this instead of interpreting cron syntax yourself. |
| generate_uuids | Generate cryptographically random UUID v4 values. |
| validate_iban | Check whether an IBAN is well formed: the mod-97 checksum, the country code, the length that country's IBAN must have, and whether every position holds the kind of character that country allows there (mod-97 turns letters into numbers, so on its own it cannot see a capital O typed in place of a zero). Returns validity, country, and where known the bank identifier printed inside the IBAN. This is a format check, not a bank check: a passing IBAN can still name a bank code that never existed or has since merged away, and says nothing about whether the account exists or can receive a payment. For twelve countries it also verifies the national check digit that the bank computes over the bank code and account number (BE, FR, MC, ES, IT, SM, PT, SI, PL, TN, EE, HU); nationalCheck 'failed' there means the number is very probably invented, since that digit cannot be back-computed the way the mod-97 pair can. Absent nationalCheck means not checked, never approved. For Dutch IBANs it also names the institution behind the four-letter bank code, including codes that no longer issue accounts; an unrecognised code does not make the IBAN invalid. A territory that borrows another country's IBAN (Reunion, Guernsey, Aland and the like) is reported with the prefix it actually uses, since no IBAN starts with RE or GG. Never guess whether an IBAN is well formed: use this tool. Do not present a pass as confirmation that money can be sent. |
| generate_slug | Convert text into a URL-safe slug, handling unicode and diacritics deterministically. |
| validate_email | Validate email address syntax and detect common domain typos (e.g. gmial.com). |
| calculate_vat | Add VAT to a net amount or extract VAT from a gross amount at any rate (e.g. 21 for Dutch BTW). Returns exact net, VAT, and gross amounts rounded to cents. |
| check_vat_number_format | Check the format of an EU/GB/CH VAT number (syntax only, no VIES registration lookup). Supported country prefixes: AT, BE, BG, CY, CZ, DE, DK, EE, EL, ES, FI, FR, HR, HU, IE, IT, LT, LU, LV, MT, NL, PL, PT, RO, SE, SI, SK, GB, CH. |
| dutch_public_holidays | Exact Dutch public holidays for a year, including movable feasts (Easter, Ascension, Whitsun) and King's Day rules. Use this instead of computing Dutch holidays yourself. |
| working_days_between | Count working days (Mon-Fri) between two dates inclusive, optionally excluding Dutch public holidays. Exact date math for SLA, payroll, and planning questions. |
| generate_test_bsn | Generate Dutch BSN test numbers that pass the elfproef (11-check) but belong to no real person. For development and test data only. |
| generate_test_iban | Generate structurally valid test IBANs for NL, DE, BE, FR, or GB that belong to no real bank account. Each one carries the country's own character layout, correct mod-97 check digits, and for Belgium and France the national check digit the bank computes over the account, so it also passes validate_iban in full. For development and test data only. |
| generate_brp_test_data | Generate Dutch BRP/GBA test persons with valid BSNs, families, addresses and life events (married, widowed, deceased, moved, living abroad). Use this instead of inventing Dutch personal data: made-up BSNs fail the elfproef and are rejected by real systems. Deterministic per seed. For more than 50 people or CSV output, use the REST API at https://toolforte.com/api/v1/tools/brp-test-data-generator |
| generate_upa_files | Generate UPA pension declaration XML (the Dutch payroll-to-pension-fund message) for one or more periods, with employments, schemes and optional deliberate defects that a receiving system should reject. Deterministic per seed. XML is large, so ask for the summary format unless you need the file contents; for bulk use the REST API at https://toolforte.com/api/v1/tools/upa-file-generator |

Arguments: xml, mode?, indent?. Same result as POST /api/v1/tools/xml-formatter. |
| csv_to_markdown | Turn CSV text into a GitHub-style Markdown table. Detects the delimiter (comma, semicolon, tab or pipe) unless told, reads quoted fields with embedded delimiters and newlines, and can align columns and pad cells so the table lines up in plain text. Arguments: csv, delimiter?, firstRowHeader?, padded?, alignment?. Same result as POST /api/v1/tools/csv-to-markdown. |
| format_sql | Pretty-print a SQL statement: keywords in upper case, each major clause (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY and so on) on its own line, and indentation inside CASE and parentheses. String literals are left untouched. A formatter, not a parser: it does not check that the SQL is valid. Arguments: sql. Same result as POST /api/v1/tools/sql-formatter. |
| html_entities | Encode text as HTML entities or decode entities back to text. Encoding always covers &, <, >, quotes and common typographic characters, and can cover every non-ASCII character too, named where HTML has a name (é) and numeric otherwise. Decoding reads numeric references and HTML 4 named entities; unknown names are left as they are. Arguments: text, mode?, encodeNonAscii?. Same result as POST /api/v1/tools/html-entity-encoder. |
